Smartphone-Guided Visible Light Modulation of RSNOs for Antimicrobial Activity via Controlled Nitric Oxide Release. [PDF]

open access: yesAdv Sci (Weinh)
A light‐activated catheter insert combines antimicrobial blue light with nitric oxide release to generate complementary oxidative and nitrosative stress, producing potent broad‐spectrum antimicrobial activity. The approach achieves greater than 4‐log reductions in bacterial and fungal viability and significantly reduces Staphylococcus aureus ...

A numerical investigation into the strength of offshore jacket platforms considering time-variant zonal corrosion subjected to alternative ship impacts [PDF]

open access: yesHeliyon
In addition to the usual loads, fixed jacket offshore platforms can be exposed to accidental loads from ship collisions. Indentation of tubular components is a significant defect that occurs when a supply vessel collides with a jacket platform, which can
